Add support for retina displays to sk_app.

The macOS view system is in "big pixel" units, so translate these
into "physical pixel" units.

To compensate, add sk_app::Window::scaleFactor() which returns the
scale factor. The viewer app is modified to apply the inverse of
this scale factor to the current zoom level.
